Yeah, that right-left stuff breaks down fast using flags. Note there is no perimeter tape with those sections and in the above example, two runs of perimeter tape does exactly the same thing only with a bit more throw-away material. I do wonder too if they are anal about an 'intended invisible line' between each flag. Can you get a five by veering out between flags? SYSTEM DESIGN UPDATE I was just on the phone ordering more flags for the next test event with my marking system. I was all happy over adding two striped-pattern flags into my color scheme until I was informed that the patterns are only printed on ONE SIDE! That means the commonly available white and yellow flags with bold stripes, dots, checker patter, or other become solid flags with no patter when the wind blows just so. Well that idea crashed in flames! You can't use a solid yellow flag and a black striped yellow flag in the same event. If the wind turns the flag printed side away it becomes a solid yellow flag! I'm back to all solid-color flags and I've slipped the problematic green and white flags back in. I did order 200 silver flags just in case. If they prove easily distinguishable from white flags, and they aren't adjacent to white in the color/difficulty hierarchy, maybe silver will allow me to drop the green flags out of the system? We shall see. Yeah white flags could get hard to see against snow, but at least they are up in the air waving around. I've had printed cards become unreadable when frost covered, whether stapled to trees or on the ground in sandwich bags. I have some flag samples coming of patterns printed on clear vinyl. Some particular color pattern may stand out sufficiently on both sides of a clear flag. We shall see. I also ordered more orange 1-3/16" tape to be able to mark the loop, and section perimeter tape in orange, with start and end gates in orange, just to see how everything but line gates in orange works out. That will either be simple stupid friendly or a bit monotonous or overbearing. We shall see!
